`abstract ResultSet` | `getOriginal()` Retrieves a `ResultSet` object containing the original value of this `RowSet` object.
`abstract ResultSet` | `getOriginalRow()` Retrieves a `ResultSet` object containing the original value of the current row only.
`abstract Object[]` | `getParams()` Retrieves the parameters that have been set for this `RowSet` object's command.
`abstract void` | `setMetaData(RowSetMetaData md)` Sets the given `RowSetMetaData` object as the `RowSetMetaData` object for this `RowSet` object.

## Public methods

### getConnection

    public abstract Connection getConnection ()
